Description
What do scientists do? Is science a belief? Is science true?
Join with Professor Lehman to explore past experiments, hear stories of great scientists, and dig into your own understanding to discover some answers together.
Starting with a discussion of what scientists do, you may be surprised at the why and how of scientists' work.
What happens when scientists disagree? How does society come to accept new theories, and why?
How important are measurements? Can we be certain of things we cannot see? Through Professor Lehman's lecture you will become comfortable with uncertainty...within reason! You will become prepared when someone makes a scientific claim - is it an observation that can be measurable? And repeated?
For instance: We all breathe air. But for centuries we didn't understand what "air" is. Explore the evolution of scientific knowledge through the example of oxygen. As we see what people believed was true has changed, we can accept the process of science. And not be fooled.
What is science without experiments? In our lecture watch Professor Lehman perform two simple experiments to demonstrate the principles of the course.
Pay attention - Professor Lehman has a sly sense of humor!
Featuring: Sir Isaac Newton, Albert Einstein, The United States Air Force, Joseph Priestley, and Antoine LaVoisier
“There’s plenty of goofiness in science and we’re still sorting it out.” -Professor Lehman
Who this course is for:
- Teens through adults curious about how science becomes "truth."
- This course is for the casual learner who wonders what it means when people say phrases such as, "Follow the science."

Our chemistry professor has taught for over three decades. Professor Lehman got his Masters of Science in Chemistry at California Polytechnic State University, Pomona, and his teaching credential at the University of California, Riverside. After spending a few years teaching middle school physical science and high school chemistry, Professor Lehman found his calling at the community college. Many of his students go on to pharmacy school, pharm tech programs, nursing courses, medical school, and forensic science degrees. After teaching for so many years he is excited to share his love of all things science with the Udemy community!
